		<div><font face="Verdana, Geneva, sans-serif" size="-1"> Motion detection excercise,
	    using a PixelBender<font color="#990000">**</font> kernal to isolate a colour,
	    red in this instance. This kernal has been programmed to look for strength
	    of colour in the red channel (pixel by pixel), and then switch these
	    pixels with white.<br />A poppy works well. If you don't have one (why not?), feel free to <i>borrow</i> one from my monitor.<br />
    The next step will be to use this colour isolation to define areas of movement
    - so we can track colour movement, for example, to track the glowing tip
    of a wand and interact with physical interfaces via gestures in front of
    a camera.<br />
    Watch this space!<br /><br />You will need a camera to see anything. There is no polite interface if you don't have one. Sorry.<br />Nick<br /></font></div>
